Backward compatibility

We recommend everyone who uses OpenCms to update to the 8.0.0 release.

OpenCms 8 is fully backward compatible to all prior 7.x versions. Templates and other OpenCms developed code from version 7.0 or 7.5 should work "out of the box" with version 8.

Users of the Alkacon OCEE packages require a new version of Alkacon OCEE for use with this OpenCms release. OpenCms 8 requires Alkacon OCEE version 3 or newer.

Compatibility with Java versions, Servlet containers and Databases

OpenCms 8.0 has been written and tested using Java 5 / 6. We have tested only with SUNs version (well actually it's ORACLEs version now) of the JDK. However, OpenCms has no dependencies to sun.* packages so it should in theory run with all compliant JVMs.

We have tested this release on the Tomcat servlet engine. OpenCms works "out of the box" with Tomcat 6.0, which we recommend. Others have reported deploying OpenCms successfully on other servlet containers like JBoss, BEA, Websphere, Glassfish and Resin Professional. We appreciate any feedback regarding other servlet containers.

On the database side, we have tested with MySQL 5.x, Oracle 9.x and Oracle 10.x, as well as PostgreSQL 8.2.x and 7.4.x, MS SQL Server 2000 / 2003, DB2 9.1 and HSQLDB 1.8.0. The automatic update wizard for OpenCms 8 supports MySQL, Oracle and PostgreSQL.

Regarding version numbers and CVS build tags

In case you want to check out OpenCms from the CVS, please keep the following in mind: The CVS tag numbers for all OpenCms 8.0 releases are "build_8_0_x", so the 8.0.0 release is tagged "build_8_0_0". Development of maintenance releases is currently done in CVS HEAD.
